1.8 Volt Low Power CMOS Oscillator
Description
The Euroquartz EMEM1018 oscillator range are 1.8 Volt supply MEMS
(Micro Electro-Mechanical System) devices offering excellent jitter and
stability performance over a wide range of supply voltages and
temperature ranges. EMEM1018 parts incorporate an all-silicon
resonator that is robust and perfoms well in high shock and vibration
environments.
EMEM1018 oscillators are available in four, industry-standard SMD
packages: 7 x 5mm, 5 x 3.2mm, 3.2 x 2.5mm and 2.5 x 2.0mm. The
part may be 'dropped in' to most PCB footprints as standard crystal
oscillators.
